CARTRIDGE-CASE.

2EGIFICATION forming part of Letters Patent No. 436,150, dated September 9, 1890.

Application filed February 11, 1890. Serial No. 340,048. (No specimens.)

To all whom it may concern:

Be it known that I, Aaron Rnnnson, a subject of. the Emperor of Austria-Hungary, and a resident of the city of Vienna, in Austria-Hungary, have invented certain new and useful Improvements in Cartridge-Cases, of which the following is a specification.

According to the presentimprovements the cartridge-case is formed of two parts, both of which are manufactured of a particular material later described.

With reference to the accompanying drawings, Figure 1 shows a central-firecartridge case, and Fig. 2 a piu-fire-cartridge case, made according to the present invention. Figs. 3

and i show the molds for manufacturing the parts of the cartridge-case.

A is the tubula part of the cartridge-case B is the head, provided with the flange Z) and with the (hamber 0, into which the primingcap is inserted.

According to the present improvementS tli'e'cartridge-case is manufactured from a pulp prepared from cordagc. 'lhc Cordagethat is to say, ships ropes or rope ends-is treated in the way usual in making tough paper from such material. small pieces, then ground, washed, and again treated in a pulping-machine. The pulp obtained is mixed with five percent. of its own weight of a solution of starch. The mixture is then suitable for the manufacture of the cartridge-cases.

- \Vithout departing from the substance of this invention, any of the following materials may be added to the cordage when a minor quality of cartridgecases is man 11 favtured, viz: linen, cotton, hemp, jute, sulphite cellulose, white or brown wood pulp or straw pulp, fine or coarse packing-rags or other rags, twine refuse, spinning refuse, cording refuse, cotton-wool, animal hairs, vegetable fibers, gypsum, chalk, potatoes, mcaly pulpy substances, such as paste, gluten, glue, and the like.

The pulp prepared as above described is put into steel or metal molds, as shown in Fig. 3, for forming the cartridge-head B, or, as in Fig. -'l, for forming the cartridge-tube A. The molds consist of the lower part E 'E',the middle part- G G, and the stamp or die H il. The die ll may be suitably engraved with an design or letters representing the quality of the cartridgecase, its caliber, the name of bone.

It is first out into' the maker, (to. .The pulp poured into the mold is subjected to a pressu P0 of about a ton, and the expressed liquid passes out through holes g, suitably arranged in the mold. The cartridge-tubes A thus made are well dried and finally polished with agate.

The cartridge-heads ll made as above described are well dried, then dipped into an oil bath, and immediately taken out and well baked for about two hours in an oven at a temperature of about to eentigrade, which causes it to attain the consistency of The cartridge-head is finally coated with a bronze paint, giving it the appearance of brass. The manufacture of the cartridgecase is completed by applying iluid glue to the cartridge-head l-i, and then inserting it into the tube A, and linally drying'it.

'l he cartridge-cases manufactured as doscribcd have the following advantages: First, the tube A, being molded and not made of rolled paper, is of uniform strength and not liable to split in firing; second, the head 13 is of less weight than a metal head and does not oxidize or cause oxidation, as it does not oontain metallic or corrosive materials; third, the gun is not liable to injury through frietion in using such cartridges, as there is no friction of metal against metal; fourth, the cartridge-case having a bone-like consistency resists injurious influences of weather, &c., and does not suffer from exposure to wet; fifth, the em-tridgc-eascs are much cheaper than those hitherto used.

I claim I 1. A cartrhlge-casc composed of two parts, the tube and the head, both of molded paperpulp, the head con-ted with oil and baked and littcd into the tube, which has its outer surface polished.

2. The mode herein described of manufacturing cart-ridgecases, consisting in preparing a pulp from cordage, pressing the same into molds to form thcsoparato tube and head, polishinglhetubc,oilingand baking the head, and fixing the head into the tube, all substantially as described.

In testimony whereof I have allixcd my signature in presence of two witnesses.
